<p>[QUOTE=&quot;Pavlos, post: 3356583, member: 96635&quot;]PLA itself is not poisonous at all, in fact, my job is to make the ideal PLA for these guys: </p><p><img src="https://www.dovepress.com/cr_data/article_submission_image/s63000/63437/figure_190.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p>Implants that will degrade inside your body, a good replacement of titanium implants and it prevents a second surgery to normally remove these titanium plates. That is however biomedical PLA, technical PLA does have some high content Tin metal (from the catalyst), but if nobody ingests it, it is fine (and even then I do not expect any problems, except if it happens many times).</p><p><br /></p><p>It sounds like a really nice idea, but I personally wouldn&#039;t put bronze coins in it, I have no idea what possible lactic acid (from degradation over time) might do with bronze, but I am pretty sure the lactic acid might react with copper to cupric lactate over time. Silver coins will be obviously fine, however, I do expect some toning of the silver over a long time, but definitely not in the short time.[/QUOTE]</p><p><br /></p>
